Abstract

A method and device for setting screen brightness, which relate to the technical field of computers. The method comprises: by using a light sensor, acquiring a brightness value of ambient light of an environment that a terminal is located in (101); detecting whether the light sensor faces away from a light source in the environment (102); if that the light sensor faces away from the light source is detected, calculating a first backlight brightness level according to the brightness value, wherein the first backlight brightness level is greater than a second backlight brightness level, and the second backlight brightness level is a backlight brightness level obtained by calculation according to the brightness value, when the light sensor faces toward the light source (103); and setting a backlight brightness of the terminal as the first backlight brightness level (104). The present invention resolves a problem that when a light sensor faces away from a light source, a detected brightness value of ambient light is excessively small, which results in an inaccurate backlight brightness level calculated according to the brightness value and a backlight function when the light sensor faces toward the light source; and an effect of improving the accuracy of the backlight brightness level is achieved.
